Title: Automatic vending machines for newspapers and the like
Inventor: MAECKEL HANS
IPC: G07F11/04
Filed: 1963-12-31
Abstract: 1,004,238. Coin-freed vending machines. LUCKENWALDER METALLWARENFABRIK VEB. Dec. 31, 1963, No. 51397/63. Heading G4V. [Also in Divisions A4 and B6] A newspaper vending machine has a reversible motor 2 which when energized, e.g. by a coin, drives a gear 3 loose on shaft 4 and having a pawl 6 on one face which drives a ratchet-wheel 7 fixed to the shaft, whereby a rope 9 is wound on pulley 8 and lifts the shelf 11 and stack 12 of papers until it lifts the expeller 13 to stop the motor via a limit switch 14. The switch 14 now reverses the motor so that a pawl 5 on its other face drives a ratchet-wheel 17 loose on the shaft and provided with pegs 18 which engage cam 19 to rotate a shaft 16 whereby the expeller 13 is cranked forward and its pins 15 push the top newspaper towards a vending orifice, after which it is retracted by spring 20. Since the expeller now drops through the thickness of one paper, it actuates the switch 14 which raises the stack by the same thickness ready for the next dispensing. When all the papers have been dispensed, the shelf actuates switch 29 to give an indication or block operation. On opening the front of the machine, a lever lifts the expeller and movement of lever 30 declutches pulley 8 and provides a brake when lowering the shelf 11 for recharging with papers.

Abstract: 1291833 Weighing CONVEYANCER Ltd 2 Jan 1970 [31 Oct 1968] 51711/68 Heading G1N [Also in Division G4] A weighing device on a forklift truck includes a strain gauge 45 responsive to fluid-pressure in an hydraulic jack supporting the forks or other load bearing members of the truck and reed switches 1, 2 actuable by a permanent magnet 4 on the carriage 3 of the truck to control a weighing sequence. In use the jack is operated to bring the arrows 6 into alignment, then the "Weigh" button 9 is pressed to close contacts 16, 17 which are electromagnetically latched by coil 18 and "lower" lamp 27 is illuminated. The jack is operated to lower the carriage to bring arrows 7 into alignment when switch 2 closes to light "stop" lamp 28. Transistor VT3 is turned on after a predetermined delay (R8C3) to energize the coil of relay RL2 which turns off VT2, after a short interval during which capacitor C2 discharges, and removes the D.C. supply from an inverter 32. During the charging time of C3 the inverter supplies A. C. to a bridge network 44, 45, 46, 54, 55, 56, 117. Unbalance voltages are developed across the rheostat 56 and fed to a phase sensitive amplifier 53 which drives the wiper of a rheostat 59 to balance the bridge and position the disc 13 of the indicator 12. However if the carriage is lowered too slowly, C2 discharges fully so that VT2 turns off, the holding circuit for switches 16 and 17 is broken and the weighing sequence has to be re-initiated by closure of switch 1. The measuring arm includes a series rheostat 44 coupled to a zeroadjust 11, a rheostat 46 for off-setting the weight of the load lifting member and a fixed resistor 117 selectable to provide a no-load simulation. A fixed resistor 92 may be switched into the bridge instead of the measuring arm to provide a 75% full scale reading on the disc 13, during a sequence actuated by "check" button 10. When the relay RL2 is energized the servomotor 95 is turned off and the disc 13 comes to rest, simultaneously the "Read" lamp 61 is lit. The disc is connected to a digital encoder (see Division G4).

Title: Dual-Circuit Brake System
IPC: F16D65/18
Filed: 1967-11-27
Abstract: 1,168,170. Dual-circuit braking systems; disc brakes. ALFRED TEVES G.m.b.H. 27 Nov., 1967 [14 Jan., 1967; 28 April, 1967], No. 53877/67. Headings F2E and F2F. A dual-circuit braking system for vehicle disc brakes comprises two opposed braking cylinders each having two pistons of identical diameter disposed one behind the other and operated by a master cylinder. In Fig. 1 the master cylinder has two pistons 23, 24 connected by a thrust rod 32 operating through a partition 22. The brake disc 1 is contacted by two friction pads 2, 3, each of which has two operating pistons 6, 7 and 8, 9, all of the same diameter. Each chamber 20, 21 of the master cylinder operates one inner piston 6 or 8 and one outer piston 7 or 9. In normal operation, when the pedal 29 is depressed pistons 6 and 8 press the pads against the disc, while pistons 7 and 9 remain still as their faces are subjected to equal and opposite pressures. If one line fails (e.g. 10), pressure will be applied to chamber 19 so that piston 9 operates the pad 2 through piston 8, and piston 6 operates pad 3 normally. The same braking force is produced by the same force on the pedal but with twice the stroke. In a modification (Fig. 2, not shown), the pedal stroke remains the same but twice the force is necessary if one line fails. This is achieved by constructing the slave cylinders in the same way as the master cylinders, i.e. two pistons connected by a thrust rod and operating in two chambers separated by a partition. The outer piston is spring-loaded to the release position. In either embodiment the master cylinder chambers may be in parallel instead of series.

Abstract: 1,235,289. Dyeing with polymerisable phthalocyanine dyes. IMPERIAL CHEMICAL INDUSTRIES Ltd. 25 Nov., 1968 [28 Nov., 1967], No. 54126/67. Heading D1B. [Also in Divisions C3 and C4] Dyeings or printings are obtained using phthalocyanine dyestuffs containing at least one group of the formula wherein R 1  and R 2  each represents H, halogen, alkyl, aryl or aralkyl and R 3  represents H, halogen, alkyl, aryl, aralkyl or a carboxylic acid or carboxylic ester group, by homopolymerising the dyestuff, or copolymerising the dyestuff with another coloured monomer which contains one or more polymerisable olefinic groups, in situ on a textile material or polymeric film. The dyeings or printings are fast to wet-treatments and solvent-treatments. The dyestuffs used are preferably derived from copper phthalocyanine. To effect polymerisation, a free radical polymerisation initiator is applied after, or simultaneously with, the dyestuff, and the initiator is activated by heat, steam or other treatment of the substrate material. Instead of using a chemical initiator, the substrate material can be exposed to radiation, e.g. UV, X-ray, gamma ray or electron beam radiation. The treatment of the material with the dyestuff monomers can be effected by suitable modification of conventional dyeing, padding or printing processes. Suitable textile materials which can be treated include those comprising cotton, regenerated cellulose such as viscose rayon, wool, silk, cellulose acetate, polyurethanes, polyolefins polyamides (e.g. nylon), polyacrylonitrile, modified poly acrylonitrile or aromatic polyester (e.g. polyethylene terephthalate) fibres; the materials may be in the form of loose fibre, slubbing, yarn or piece goods. Polymeric films which can be treated include those of polyester, polyamide, polyimide, polyurethane, polyvinyl materials and polyolefins.
